a ng mass is being held up by a string which is connected to two other strings as shown in the figure below. What is the tension in all three strings? 4) A uniform horizontal bar of length L = 5.0 m and weight 140 N is pinned to a vertical wall and
A block of mass M = 15 kg is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal and the right string makes an angle θ = 50° with the horizontal. What is the tension in the left string? (Assume the ring where the strings come together is massless.) Tleft =
A ball of mass 5.0 kg is suspended by two wires from a
horizontal arm that is attached to a vertical shaft, as shown in
the figure. The shaft is in uniform rotation about its axis. The
rate of rotation is adjusted until the tensions in the two wires
are EQUAL. At that speed, what is the radial acceleration of the
ball?

A rigid, uniform, horizontal bar of mass m1 and length L is
supported by two identical massless strings. (Figure 1) Both
strings are vertical. String A is attached at a distance d<L/2
from the left end of the bar and is connected to the ceiling;
string B is attached to the left end of the bar and is connected to
the floor. A small block of mass m2 is supported against gravity by
the bar at a distance x from...

12. A 3.20 kg block is attached to a light and firm string and is placed on top of a horizontal platform. A horizontal force F-45.0 N is pulling the block to the right. The coefficient of the kinetic friction between the block and the platform is 0.240. The other end of the string is connected to a block of mass 2.80 kg that is hanging straight down as shown in the figure below. The blocks are...
3.) A uniform beam, mass 15.0 kg. hangs motionless, supported by three cables as shown in the figure. A 12.0 kg mass hangs from a point one- quarter of the length of the beam from the left end. T=? What is the tension in the vertical cable attached at the left end of the beam? m
Word Problems You must show all of your work to get full credit. Write as neatly and organized as possible. Put a circle around your final answer. 1.) (10) A cylindrical pulley of mass M 20.0 kg has an inner shaft of radius r 40.0 cm while the outer radius is R 1.00 m, The inner part is attached to the ceiling by a light string and to balance the system the outer part is attached to a mass m...

5. Solve problems (a) to (c) below. (a) A 60.0-kg block is attached to a massless spring with force constant k = 575 N/m. (1) Find the natural frequency for this simple harmonic oscillator, in Hatz (cycles/sec). (ii) If the amplitude is 0350 m, predict the maximum speed of the block (for Instructor use only) (b) A siren has an intensity of 10W/m²at a distance of 10.0 m away. What is its intensity at a...
An object of mass m1 = 4.00 kg is tied to an object of mass m2 = 3.40 kg with String 1 of length ℓ = 0.500 m. The combination is swung in a vertical circular path on a second string, String 2, of length ℓ = 0.500 m. During the motion, the two strings are collinear at all times as shown in the figure. At the top of its motion, m2 is traveling at v = 5.30 m/s. Two...
